An ACK isn't really a request, in the sense that you don't send a response when you receive it. Thus, when you receive an ACK that doesn't match an INVITE (of course it CAN'T match a transaction since it uses a new, unique, branch-id in its Via), all you can do is drop the message. Of course you can log the dropped message, but that's not a protocol issue. frank _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
